Semiconductor light emitting devices with a high-power output and a broadband spectrum characteristic are accepted as a promising light source for the optical sensing system. However, the characteristics of a high-power and a broadband spectrum are in a trade-off relationship. We have successfully fabricated a broadband emitting diode by multiplying emission areas. This device has the performance of 1.9 times of spectrum width compared with the conventional devices of indentical outputs. This… CONTINUE READING
